   Do not let this come to a boil until sugar has completely dissolved.
4. 4
   Turn the heat up a bit and continue cooking to the hard ball stage (250F).

7. 7
   Stir in the vanilla.
8. 8
   Pour candy in a thin sheet onto a greased slab.
9. 9
   (I don't have a slab. I turn a large metal baking pan upside down and grease the bottom- works great!).

    Mark into squares while still warm, creasing it deeply.
11. 11
    Break into pieces as soon as it is cool.
